Dispersion-Engineered Compact Twisted Metasurfaces Enabling 3D Frequency-Reconfigurable Holography

Caption

Architecture of the proposed compact twisted meta-device for frequency-reconfigurable holography. The meta-device integrates cascaded radiation-type metasurfaces (RA-M) with phase-only metasurfaces (P-M), where in-plane rotational control of the P-M through angle α enables dynamic hologram switching across designated imaging planes.
